Process: Add a test for waitForReadyRead on error channel

Browse Source 
Currently it works only in case of ProcessLaucher implementation.
The issue with QProcess implementation is that we need to
select the active channel in advance with QProcess::setReadChannel(),
what really doesn't make sense, since we can't predict on which
channel we will receive the data.

Currently we don't have setReadChannel() method inside Process API.
